For "particulate filter" read HEPA filter: it is what I use but couldnt remember the name. If I can detect the difference between it and a standard filter the particles are still coming out the back and those that cant are still ingesting them. Seems not a good idea to me: one day they may notice but they could be helping their lungs now. Theres so much we cant do anything about like car exhausts and particles from the tyres of electric vehicles that dont have them. Seems a good idea to improve where we can.
